Road cleaner clean rubbish operation principle be:It please join Fig. 6, when carrying out cleaning work, dustbin 130 is located at
Horizontal level is placed, and air inlet 111 is engaged with the second ventilating opening 1312 of first chamber 131;Control suction inlet valve 153 is beaten
Sweep-up pipe 152 is opened, control wind turbine valve 113 opens air inlet 111, and control dustbin valve 134 opens first chamber 131
The second ventilating opening 1312 and close third venting mouth 1313, control Dump gate 137 close discharge port 136, control discharging ventilation
Valve 139 closes discharging ventilating opening 138, while starts the wind turbine 110 of road cleaner, and the negative pressure that the operating of wind turbine 110 produces exists
Airflow direction as indicated by arrows in fig. 6 is formed between the wind turbine 110 and suction nozzle 151 of road cleaner, rubbish is sucked from suction nozzle 151
In 3rd chamber 133 of dustbin 130, the dust laden air that the 3rd chamber 133 of dustbin 130 is entered with rubbish is logical through the 5th
Strainer 1316 on air port 1315 filters out bulk rubbish and enters second chamber 132, then by second chamber 132 via the 4th ventilation
Mouthfuls 1314 filter into dust cleaning cases 106 through dust-extraction unit 120, the cleaned air after filtering is out of dust from first chamber 131 the
Two ventilating openings 1312 suck wind turbine 110, then 112 row of fan outlet through wind turbine 110, into air, road cleaner is cleaning
Also there is dedusting and purification air while rubbish.
Fig. 7 is that the road cleaner of present pre-ferred embodiments lifts the air-flow flowing signal before dustbin in discharging
Figure, Fig. 8 is that the road cleaner of present pre-ferred embodiments lifts the air-flow flow schematic diagram after dustbin, Fig. 9 in discharging
Air-flow flow schematic diagram of the road cleaner of present pre-ferred embodiments in discharging in dust cover, also referring to Fig. 7,
Fig. 8 and Fig. 9, before road cleaner lifts dustbin 130 in discharging, controls wind turbine valve 113 to close air inlet first
111, control suction inlet valve 153 closes sweep-up pipe 152, and control dustbin valve 134 closes the second ventilating opening of first chamber 131
1312 and third venting mouth 1313 is opened, control discharging Ventilating valve 139 opens discharging ventilating opening 138, and Dump gate 137 is also at this time
In the state for closing discharge port 136, the outlet stretching, extension of control dust cover 160 close to ground and with ground have it is certain between
Gap, starts the wind turbine 110 of road cleaner, and the negative pressure that the operating of wind turbine 110 produces can pass through the air in the exit of dust cover 160
Discharging ventilating opening 138 is sucked in the 3rd chamber 133 of dustbin 130, and in the wind turbine 110 and dust cover 160 of road cleaner
Between form the airflow direction as shown in Fig. 7 arrows, the air from the dedusting air outlet 122 of dust-extraction unit 120 out can only at this time
Air inlet 111 is entered by dust removing tube 140 and is discharged by fan outlet 112.
Wind turbine 110, which operates caused negative pressure, can be transferred to the outlet of dust cover 160 and the gap location of ground surrounding, anti-
After the exit of dust hood 160 forms negative pressure, the operating status of wind turbine 110 is kept, dustbin 130 is lifted, control Dump gate 137
Open discharge port 136 and carry out discharging, road cleaner is formed such as Fig. 8 arrows institute under the negative-pressure ward effect of wind turbine 110 at this time
Show airflow direction, wherein, the air of the exit suction of dust cover 160 is divided into the 3rd chamber that two parts enter dustbin 130
In 133, as shown in figure 9, a portion air enters in the 3rd chamber 133 of dustbin 130 from discharge port 136, another portion
Air is divided to enter the 3rd chamber 133 of dustbin 130 from discharging ventilating opening 138.When dumping rubbish, dust cover 160 will can be fallen
Rubbish barrier, and the dust evoked by rubbish also can suck dustbin 130 again via 120 mistake of dust-extraction unit by negative pressure immediately
Filter, so that airborne dust when achieving the purpose that to suppress road cleaner discharging.When amount of dust is larger, when discharging, can select to improve
110 rotating speed of wind turbine, i.e., can also be adjusted the rotating speed of wind turbine 110 in discharging.
When the quantity of refuse in dustbin 130 is larger and during comparatively dense, during 136 discharging of discharge port is opened, rubbish
It is possible to discharge port 136 can be sealed completely, the air-flow of 160 inlet of dust cover can not enter dustbin from discharge port 136
In 130, if being not provided with discharging ventilating opening 138, wind turbine 110 is even opened, can not also form smoothly current path, because
This, can produce that airborne dust is excessive to outside dust cover 160, and road cleaner of the invention is by adding discharging ventilating opening in this moment
138 and discharging Ventilating valve 139, so that divulging information between wind turbine 110 and dust cover 160 via discharging before Dump gate 137 is opened
Mouth 138 is initially formed current path, and therefore, after the opening of Dump gate 137, the outlet of dust cover 160 has just formed negative pressure, and
The negative pressure state in the exit of dust cover 160 can be always maintained at, efficiently avoid when just opening Dump gate 137 because of quantity of refuse mistake
It is big to seal discharge port 136 and block current path to prevent air-flow from entering in dustbin 130, to make road cleaner in discharging
Influence from rubbish by Dump gate 137, forms good current path in 130 internal upper part region of dustbin, realizes discharging
When negative pressure demand, it is therefore, excessive all without there is dust in whole discharge process, cause dust pollution.The road of the present invention
Car is cleaned in cleaning work and discharging without water demand, the adverse effect for avoiding climatic factor from bringing, can apply to water shortage
Area, use scope are wider.
Further, by setting different the first gas channel of Valve controlling (i.e. institutes of connecting pipe 114 in diverse location
Passage) with the second gas channel (passage i.e. where dust removing tube 140) connect or blocking, carried out in road cleaner clear
When sweeping operation (dustbin 130 is horizontal at this time), dedusting air outlet 122 passes through the first gas channel and air inlet
111 connections;In road cleaner discharging (dustbin 130 is from horizontal level status transition to lifting state at this time), dedusting goes out
Air port 122 is connected by the second gas channel with air inlet 111.Wherein, by 114 shape of first chamber 131 and connecting pipe
Into the first gas channel, the second gas channel is formed by first chamber 131 and dust removing tube 140.Dust removing tube 140 is affixed directly to existing
Have on dustbin 130 and chassis 102, do not take up space, it is simple in structure, easily realize.By controlling wind turbine valve 113, suction nozzle valve
153rd, dustbin valve 134 and discharging Ventilating valve 139 open and close corresponding passage to meet that road cleaner is cleaning
To the conversion of current path when operation and discharging.It is low when required negative pressure is than cleaning work during due to discharging, dust removing tube 140
The current path formed can meet its requirement, at the same can according under different operating modes to the demand of air quantity and negative pressure to wind turbine into
Row speed governing, has effectively saved the energy.
The road cleaner provided by the present invention with discharging dust removal device is described in detail above, herein
Apply specific case to be set forth the principle of the present invention and embodiment, the explanation of above example is only intended to help
Understand the method and its core concept of the present invention;Meanwhile for those of ordinary skill in the art, according to the thought of the present invention,
There will be changes in specific embodiments and applications, in conclusion this specification content should not be construed as to this
The limitation of invention.
